Implantology 101

To begin with, let’s understand the anatomy of a natural tooth. A natural tooth has a root that is embedded in the bone and encased by the gum tissues. The part that emerges from the bone and is visible in the mouth is termed the crown. Dental implants are based on the same design pattern. Implants act like a metal substructure or a “root” on which fixed, replacement teeth, or a “crown” can be placed.

Dental implants are a permanent solution for people suffering from missing teeth, failing teeth and other chronic dental problems because they function, fit and feel exactly like a natural tooth. Medical grade titanium, the chief component of dental implants, has the unique ability to fuse with the natural cells of the body over a period of time. This anchors the implant to the bone providing a solid connection which follows through as good long-term prognosis.

Dental Implants have several advantages over conventional removable prostheses, crowns and bridges:

  • 1. Since there is no fear of dislodgement, you can eat and smile just as freely as you did when you had your natural teeth.
  • 2. The neighboring natural teeth are not affected in any way.
  • 3. Dental implants stimulate the bone, keeping it healthy and preventing further degeneration.
  • 4. Permanent fixed solutions are possible for single tooth, multiple teeth and the complete dentition.

As in other fields of dentistry, adequate case assessment and treatment planning is a mandate for satisfactory implant treatments. Each patient presents a unique set of problems and treatment needs. Only by taking into account their individual requirements—anatomical, functional and aesthetic—do we achieve a realistic, predictable and satisfactory outcome.

During the planning stages, many factors are considered for dental implants including patient expectations and financial and time constraints. In any given case, there are usually several treatment options available with the possibility of using different materials or procedures. Once the evaluation process is completed, a multi-disciplinary treatment plan is presented to the patient. Full patient education and information is an integral part of our treatment protocol.

The standard diagnosis and treatment plan at SIAD includes:

  • 1. Dental and social history
  • 2. Medical history
  • 3. Extra-oral examination including lip and smile lines
  • 4. Intra-oral examination including full periodontal charting
  • 5. Diagnostic imaging
  • 6. Additional investigations
  • 7. Photography
  • 8. Diagnosis and treatment plan presentation
  • 9. Written treatment plan and cost estimate
  • 10.Patient education and informed consent
  • 11.Communication with other members of the team and the referring practitioners

One of the cardinal rules in implantology is that the implant placement surgery should be prosthetically driven. The desired outcome should be first planned and accordingly the treatment plan should be formulated. According to the restorative requirements of the final case, treatment planning should include discussion of, not only the recommended treatment, but all reasonable alternatives such as conventional options, their relative advantages, disadvantages and limitations. Thus, a prosthetically driven treatment modality helps us achieve predictable results consistently.

Implants can be placed at different times depending on the techniques used and patient factors. This may range from immediate placement following extraction to delayed placement after the bone heals completely over the implant.

Just like all our procedures, an informed and patient-centric approach governs our dental implant procedure. At all times, suitable quality surgical armamentarium and equipment including resuscitation equipment are available.

Our team of implantologists have mastered:

  • 1. Aseptic surgical technique: Prevention of cross-contamination is achieved by the use of full sterile set of surgical drapes and gowns for the operating team and the patient. Sterilisation and storage of surgical instruments and components conforms to international policies and guidelines.
  • 2. Pain and anxiety control: The administration of appropriate type and dosage of local anaesthesia along with other pre-medications is done by a certified anesthesiologist who is present throughout the surgical procedure.
  • 3. Atraumatic surgical technique: All our surgical designs are aimed towards minimum post-surgical co-morbidity.
  • 4. Knowledge of surgical anatomy and vital structures: Intrinsic knowledge of the different grades of bone quality optimizes primary stability.
  • 5. Management of complications: Experienced in Basic Life Support and Advanced Cardiac Life Support, our certified dental nurse attends throughout the procedure of the surgery.
  • 6. Provision of temporary restorations: Provisional restorations, be it single crowns, bridges or fixed full arch restorations can be prepared before and placed immediately after placement of the dental implants.

Implant restorations are formulated based on a number of factors. To enumerate a few:

  • 1. Bone quality and quantity
  • 2. Stability of the implants
  • 3. Occlusion and parafunctional habits
  • 4. Aesthetic and functional requirements of the patients

Implant restorations can be of a number of types and can be broadly classified as removable and fixed. Full fixed denture results in restoration of facial esthetics, cutting down years in your appearance. Since we primarily strive to provide fixed dental solutions to our patients we will expand on that subject.

  • 1. Fixed implant restoration for a single tooth: A single implant crown can be either screwed or cemented, both indicated in different clinical scenarios. A single implant crown appears to emerge perfectly from the gums giving it a natural appearance.
  • 2. Fixed implant restoration for short span or medium span bridges: Multiple implants can be used to replace multiple missing teeth. Again, these can be screw or cement retained.
  • 3. Fixed implant restoration for full arch bridges: Multiple implants can be used to provide a solution where all teeth in an arch are missing.
  • 4. Fixed implant restoration for full arch hybrid bridges: In some cases, the provision of a screw retained full arch fixed solution is not possible. In these instances, it is possible to produce a fixed bridge structure with separate crowns in the areas where implant angulation is unfavorable.

Digital technology has made a marked difference to the dental care industry, particularly dental implantology. The move from analogue to digital has the potential to make treatment planning more sophisticated, surgery safer and produce higher quality restorations. At SIAD we employ several advanced digital techniques, all available in-house.

Our team of implantologists have mastered:

  • Virtual treatment planning and guided surgery
    Cone Beam Computed Tomography (CBCT) 3D images of craniofacial structures which can be studied for precise implant placement. These images also provide important information regarding bone quality, bone availability and important anatomical structures. A software is then used in the production of a surgical stent that guides the positioning of the implants during surgery, making the process highly predictable. This pre-planning also facilitates the pre-operative manufacture of temporary restorations that can be fitted immediately after placement of the implants.
  • Digital impression techniques
    Digital impression systems use an intra-oral scanner to capture an image of a tooth (or teeth) preparation or an implant. This image is then electronically transferred to a manufacturing facility that fabricates a working, articulated model. From this model, a multitude of different restorations can be fabricated — crowns, bridges, inlays/onlays, veneers and implant abutments are all possible.
  • Computer-aided manufacturing restorations
    A digital information can be generated from either a conventional cast or with an intra-oral scanner. The digital information is the used to design and construct a wide range of restorations. This method increases the accuracy of fit of restorations while providing greater durability.
